BACKGROUND: Following Pennsylvania's motorcycle helmet law repeal, motorcycle collision (MCC) rates were fixed; however, injuries increased. We investigated post-repeal injury severity. We hypothesized helmeted (H) motorcyclists would have better outcomes than unhelmeted (UH) motorcyclists and outcomes would worsen post repeal.
METHODS: We retrospectively reviewed (7/1/1998-7/1/2023) MCC patients in the Pennsylvania Trauma Outcome Study database. We compared H and UH patients and Pre- and Post-repeal data (Pre:1998-2002; Post:2003-2023). Adolescent and geriatric subgroup analyses were performed.
RESULTS: We included 36,943 patients: UH:14,069 and H:22,874. UH had higher ISS (p < 0.001), more severe head injuries (p < 0.001), and greater mortality (p < 0.001). Mortality was higher in UH geriatric motorcyclists (p < 0.001) and similar in adolescents (p = 0.129). Despite decreased helmet use post-repeal, ISS (p = 0.003), severe head injuries (p < 0.001) and mortality (p = 0.021) decreased.
CONCLUSIONS: Overall, 62% of motorcyclists wore helmets. Although helmet use decreased post-repeal, outcomes were comparable. Decreased helmet use leaves motorists vulnerable to head injuries and worse outcomes.
